Aspiration catheter with shaped distal tip

An aspiration catheter, comprising:

• a catheter shaft having a proximal end region, a distal end region and a lumen extending therein;
• a distal tip member having a length, a central longitudinal axis, a lumen extending therein and a distal opening, wherein the distal tip member is coupled to the distal end region of the catheter shaft;
• a guidewire shaft having a proximal end region and a distal end region;
• wherein the guidewire shaft extends within at least a portion of the lumen of the catheter shaft and the lumen of the distal tip member;
• wherein the distal tip member comprises a distal facing outer surface surrounding the distal opening of the distal tip member;
• and
• wherein a first portion of the distal facing outer surface of the distal tip member lies in a first plane perpendicular to the central longitudinal axis, and a second portion of the distal facing outer surface of the tip member extends proximally from the first portion of the distal facing outer surface, the second portion lying in a second plane at an acute angle to the central longitudinal axis.
